Evaluation for 6.2a
Materials support educators in guiding students to share and reflect on their problem-solving approaches, including explanations, arguments, justifications, and multiple points of entry.
The 7th Grade Math Practice Teacher Edition supports educators by asking students questions that require them to share their problem-solving approach. In the TEKS lesson “Qualitative and Quantitative Predictions,” the student task provides a real-world scenario where students have to determine if the solution is correct. The question asks, “Is she correct or incorrect, and how do you know?” This allows students to explain and justify their problem-solving approach to the situation.
The materials provide opportunities for students to explain their reasoning, compare strategies, and communicate mathematical thinking during collaborative activities and discussions. In the “Sample Space” activity, students work with a partner to develop an organizational system, describe their method, and justify how they determined all possible outcomes. In the “Experimental Probability” activity, students design simulations, select appropriate models, analyze results, and communicate conclusions based on collected data. The Supplemental Math Teacher Guide further emphasizes communication, justification, and reasoning through structured discussions, opportunities for students to explain reasoning orally and in writing, and prompts that encourage students to compare solution methods and reflect on their mathematical thinking.
In the TEKS lesson “Probabilities and Complements,” the lesson notes prompt students to engage in a turn-and-talk to discuss possible problem-solving strategies before solving the problems. Students then share their ideas with the class and respond to their peers by explaining whether they agree or disagree and why. The educator encourages students to consider multiple approaches by asking, “Did anyone else solve this a different way?” These instructional moves encourage students to explore, understand, and justify multiple approaches to solving problems. Asking students whether they agree or disagree creates healthy, mathematical arguments.
